Solar Thermal; Organic Rankine Cycle; Distributed Power Generation
Abstract :
[en] A solar thermal organic Rankine cycle (ORC) can provide affordable energy supplies in remote regions. The
advent of low-cost medium temperature parabolic trough collectors and ORC technology taking advantage of
mass produced fluid machinery from HVAC industries are enabling developments for the production of small
scale autonomous power generation units. Construction and testing of this type of system is discussed,
including benchmarking of scrolls expanders (up to 75% isentropic effieiency) and the field testing of solar
collectors (50% thermal efficiency at 150°C operating temperatures) with a nominal cost of $80 m-2. These
results have led to the construction of a full-scale 3kW solar ORC power system designed to support a rural
health clinic in Lesotho in southern Africa.
